The csg2csg tool is a minimal dependency Python3 based program to facilitate the comparison of radiation transport Monte Carlo codes. can currently parse MCNP and OpenMC geometry descriptions, it subsequently export MCNP, FLUKA, PHITS, Serpent files. This translation achieved by reading input into class system objects corresponding surfaces, cells, materials so on. are then translated ‘generic’...

The MCNP code is a general Monte Carlo N-Particle Transport program that is widely used in health physics, medical physics and nuclear engineering for problems involving neutron, photon and electron transport. However, due to the stochastic nature of the algorithms employed to solve the Boltzmann transport equation, MCNP generally exhibits a slow rate of convergence. In fact, engineers and scie...

introduction: radioiodine therapy is an effective method for treating thyroid cancer carcinoma, but it has some affects on normal tissues, hence dosimetry of vital organs are important to weigh the risks and benefits of this method. the aim of this study is to measure the absorbed doses of important organs by mcnp (monte carlo n particle) simulation and comparing the results of different method...

---------------------------------------------------------------------***--------------------------------------------------------------------Abstract The dose distribution in irradiation room and the dose rate at each dwell position of 60Co irradiator SVST-Co-60/B have been calculated using MCNP code. The calculated results are useful information to estimate radiation safety and design irradiato...

The NEAR station is the newest experimental area of n_TOF facility at CERN, utilizing spallation process to generate extremely high neutron flux within a broad energy spectrum. As part campaign for determination beam spectral features, numerous foils have been irradiated last year and induced activities were measured implementing HPGe detector.
 Experimental data analysis foil’s gamma-ray ...

BACKGROUND High-molecular-weight phthalates in indoor dust have been associated with asthma in children, but few studies have evaluated phthalate biomarkers in association with respiratory outcomes. OBJECTIVES We explored the association between urinary concentrations of phthalate metabolites and current asthma. METHODS In a cross-sectional analysis, 11 metabolites of 8 phthalates [includin...

The weight window variance reduction method in the general-purpose Monte Carlo N-Particle radiation transport code MCNP has recently been rewritten. In particular, it is now possible to generate weight window importance functions on a superimposed mesh, eliminating the need to subdivide geometries for variance reduction purposes. Our assessment addresses the following questions: (1) Does the n...
